Online Particle Counter

The LPC-O on-line particle counter is based on the principle of photoresistance (shading) method designated by the International Hydraulic Standards Committee, and is developed according to national and international standards such as GB/T 18854-2002 (ISO11171-1999), which is specially developed for the level of polluted particles in liquids. Detection device. Can provide fast, accurate, reliable and repeatable test results. The operation is simple and convenient, and it is suitable for on-line monitoring of various oil systems. It is also possible to connect two (or more) slaves to the same host or platform for comparison test, with simple operation and flexible combination. It can be widely used in aviation, aerospace, electric power, petroleum, chemical industry, transportation, port, metallurgy, water treatment, machinery, automobile manufacturing and other fields.
